Juno has begun to unveil Jupiter — peeling apart its interior by measuring gravity and magnetic fields, using microwaves to probe its atmosphere down to 100s of km, exploring its polar and extended ...

However, it’s essential to note that this alignment is an optical illusion, as each planet follows a widely varying elliptical path around the sun.The notion that the planets in our solar system ...

To grasp this concept, let’s delve into the orbital mechanics of our solar system. Each planet, including the six involved in this alignment (Venus, Mars, Jupiter, Saturn, Uranus, and Neptune ...

Comets Comets are formed of rocky material, dust, and water ice. Many have highly elliptical orbits that bring them very close to the Sun and swing them deep into space, often beyond the orbit of ...

The elliptical plane, the Sun's path through the sky, is home to all the planets as they orbit the Sun. In January 2025, Venus, Mars, Mercury, and Jupiter are expected to gather in close proximity ...
